He grew up as Paul Hewson and says he "can't imagine it any other way".
"The way you see the world is shaped way before you go into the world. It's shaped through the way you see a community.
"It's shaped through the way you see a street," he said.
"I live comfortably all over the world and people say it's incredible that you are really a 'wherever I lay my hat, that's my home' person.
"But I am partly that because of the way I grew up in Finglas -- sleeping on a couch, or because my mother died when I was a kid I was in the house on my own a lot of the time, so I'd knock on the door of the Hanveys at teatime, you know, or the Rowens at lunchtime.
"It might be London, it might be New York, but that ability to feel comfortable where I am was definitely instilled in me on Cedarwood Road."
In a new book Finglas: A People's Portrait penned by RTE journalist Samantha Libreri, Bono tells how he became best friends with neighbour Derek Rowen from an early age.
The pair did everything together including changing their names to Bono and Guggi.
"He lived in a very eccentric situation because they had so many kids in the house. But that wasn't what made it eccentric," Bono said. "What made it eccentric was their father, Robbie Rowen, was big into the Herald small ads, so he was sort of a compulsive buyer of motorcycles and old cars."
He got his first job aged 15 in Superquinn, but didn't last very long. But he said that he continued to pursue a career in retail in a way working for Guggi's dad, selling calendars and potatoes.
